What is Overclocking and Motherboard?

The motherboard (mobo) is the heart of the PC system. It is the electronic board with sockets for the CPU(s), RAM, PCI-e, PCI, HDDs, FDDs, and often, LAN connections, sound, and firewire. The ATX mobo form factor is about 12"x9.6". You could google for more info.

Overclocking generally refers to using the mobo through its BIOS (Basic Input Output System) settings to increase the speed of the CPU and RAM over the manufacturer's specifications. Other overclocking is increasing the Graphics Processor Unit's (GPU's) memory speed over the manufacturer's stock settings using software, or by physically altering the device.
